This watch was originally
spec'd to 20 SPY and was based on the same 196 kHz technology as the
PSR 10, but with the addition of a date feature.
Like its 10 SPY sibling, the PSR 20 has also suffered from a fairly dire
inability to maintain its accuracy.

This particular watch has not yet been subjected to any
tests, as it resides thousands of miles away, in the UK. I shall, however, give
it the full treatment of tests when I am able so to do.
